This invention relates to record card controlled machines and moreparticularly to the printing mechanism of such a machine in whichalphabetical printing is desired.

It is the objectof this invention therefore to provide means forselecting groups of printing elements and single printing elementswithin said groups by means of a single element.

I Various other objects and advantages of my invention will be obviousfrom the following particular description of one form of mechanismembodying the invention or from an inspection of the accompanyingdrawings; and the invention also constitutes certain new and novelfeatures of construction and comparts hereinafter set forth and claimed:

In the drawings:

Fig. 1 is a detailed elevation of type selecting and printing mechanism.

Fi 2 is the same as Fig. 1 shown in the position of selecting a typeelement for print- Tig. 3 is a tabulation showing the letter groups andthe index positions associated therewith.

Fig. 4 shows a portion of a record card punched to spell a word.

This printing mechanism may be substituted for or used in part with theprinting mechanism shown and described in the application of C. D. Lake,Serial No. 639,153, filed May 13, 1923, now Patent No. 1,822,594. Asthis invention only concerns the printing and selection of the printingelements, the card feed, brush sensing mechanisms and controls have notbeen shown, they being the same as described in the Lake applicationmentioned above. The impulses transmitted from the sensing brushes byvirtue of perforations in the cards passing the brushes effects theprinting magnets to select the proper notch 1n the type bar carrier inthe same manner and thereforefor the sake of simplicity the type barcarrier and coacting selecting mechanisms only are shown.

In the preferred forin of embodiment there may be provided a cross head10 which is moved upwardly in timed relation to the passage of recordcards beneath sensing brushes, not shown, situated in another part ofthe machine. As the method of card feed and the use of sensing brushesis generally known and fully described in the application to Lakepreviously mentioned and per se form no part of the present invention,it is deemed unnecessary to illustrate or explain them in detail. A comb11 fixed to the cross head 10 has slidably mounted therein a pluralityof type carrier members 12. Abutting the end of each of these members isa lever 13 pivoted to a bracket 14 fixed to the cross head. The lever 13is biased upwardly by the spring 15 so that when the cross head risesthe members are raised by spring pulled lever 13 until such time as thelocking pawl 16 engages one of the teeth 17 integral. with the. member12 at which time the member 12 is halted and the continued. rising ofthe cross head causes the lever 13 to yield through the resiliency ofthe spring 15. Integral with the upper end of the member 12 is a rack 18which meshes with a gear 19 pivoted at 20 to a lever 21 said lever beingpivotally mounted at 22 to a bar fixed to the frame of the machine (notshown). The lever 21 is biased by a spring 23 in a clockwise directionabout its pivot 22 to normally hold the gear 19 in mesh with the rack18. Fixed to the gear 19 is a disk 24 having on its periphery raisedalphabetical ty e indicia 25. As the number 12 rises the dis 24 rotatesin a clockwise direction and the teeth 17 pass the locking pawl insynchronism with the passage of the index point positions of the cardunder the sensing brushes in another part of the machine. Thus when thesensing brush encounters a perforation it releases the pawl coactingwith its corresponding type carrier member to engage the notchcorresponding to that particular index point position. Thus, forexample, if a card is perforatedinthe fifth index point position of thecolumn corresponding to the mechanism shown in Figs. 1 and 2, the member12 will rise-in synchronism with the travel of the card and as thesensing brush encounters the perforation at the fifth index pointposition the fifth notch 17 will be opposite the locking pawl 16 and themagnet 27* will receive an electric impulse by virtue of the contactmade by the sensing brush through said perforation.

Said impuse energizes magnet 27 and releases the locking pawl to engagethe notch 17, and the mechanism is timed to bring the E type indiciainto printing position when; the member 17 reaches its final lockedposition prior to the printing operation.

It will be noticed that the alphabet is divided into three groups AI,JR, SZ (Fig. 3) these groups being assigned to the index point positions1-9 inclusive, column 28 (Fig. 3) representing the index point positionsrelative to the alphabet. Thus the index point position 9 may designateeither of the three letters A, J, S or the position 8 may designateeither of the letters B, K. T, and so on as clearly shown in Fig. 3. Thealphabetical type therefore is placed around the periphery of the disk24 ina corresponding manner, thus A, J, S, B, K, T, C, L, U, etc. asshown in Fig. 1. The selection of one of the three letters for a givenindex point position is determined by the presence or absence ofperforations at the 0 index point position or at both the O and 11 indexpoint positions If a perforation appears at the 6 index hole positiononly in a column the letter D will be printed; if at the 6 and 0 indexpoint posi-' tions, the letter M will be printed; and if in 1 additionto the perforations in the two positions ust mentioned there is a thirdperforation encountered at the 11 index point position, the letter Vwill be printed. Fig. 4 illustrates how a card may be perforated tospell the Word Hot which is made up of three letters, one from eachgroup. Although the the 0 or 11 index point position in the preferredembodiment described herein, it will be understood that these holes mayfollow the primary selection or first hole at any position following thesame.

The locking of the member 17 in the proper' position to cause adesignated letter to be printed is accomplished by the pawl 16 which ispivotally mounted atc28 to a lever 29 and is biased in a clockwisedirection by the spring 30. The lever 29 is pivotally mounted on a rod31 which extends across the printing bank of the machine, said leverbeing normally held in the position shown in Fig. 1 by the action of thespring 32 fastened to said lever at one end and to the frame of themachine (not shown) at the other.

A latch 33 pivoted at 34 supports the arm 16 of the locking pawl 16normally holding it out of contact with the notches on the member 17. Alink 35 pivotally connects the latch 33 with an armature lever 36, saidlever being pivotally mounted at 37 to the frame of the machine. A.spring 38 biases the armature lever 36 in a clockwise direction therebynormally holding the armature away from its coacting electromagnet 27and holding the latch 33 in latching position. Pivotally mounted to thelink 35 is a pawl 38 coacting with ratchet teeth 39 on the peripheryof adisk 40, said pawl being held in coacting relationship with said ratchetteeth by means of the spring 41. The disk 40 is rotatably mounted on arod 42 which is supported by the frame of the machine (not shown). Thedisk 40 is biased in a clockwise direction by a coiled spring 43, oneend of which is fixed to said disk and the other end to the rod 42. Inaddition to the ratchet te'eth 39, the disk 40 has provided on itsperiphery a second series of ratchet teeth 44 and three position steps45, 46 and 47 with which the lever 29 coacts to position the proper typeelement for printing. A pawl 48., pivoted at 49 and biased in acounterclockwise direction by spring 50 coacts with the ratchet teeth44. The end of the pawl 48 is fastened by a pin and slot connection to alink 51 the other end of said link being pivotally fastened to anarmature lever 52, pivoted at 53 and coacting with an electromagnet 54.Said armature lever 52 is resiliently held away from its coacting magnet54 by a spring 55. Fixed to the link 51 is a pin 56 which coacts withthe pawl 38 to withdraw it from the ratchet teeth 39 when the magnet 56is energized.

In the description of the operation of this mechanism let'it be assumedthat the letter Wis. to be printed in which case the mechanism will takethe position shown in Fig. 2. This will require a perforation at the 5index point position on the card, one at the 0 index "point positionandone at the 11 index point position, all in thejsame column. secondand thlrd control holes are shown in 1 As the card passes under thesensmg brush, the members 17 will rise in synchronism therewith so thatwhen the perforation at the 5 index point position is under the brush,the stop pawl 16 will be opposite the 5th notch 17 When the brushencounters the perforation an impulse is sent through the correspondingprinting magnet 27 attracting its coacting armature lever 36 andWithdrawing the latch 33 so that the locking pawl 16 turns clockwiseabout its pivot and engages the notch 17, then opposite said awl. thearmature lever 36 is attracte by the magnet 27 the link 35 is moved tothe right carrying the pawl 38 which is engaged in the ratchet teeth 39.This action rotates disk 40 in a counterclockwise direction so that thestop pawl 48 engages .the next succeeding right hand ratchet tooth 44and holds the disk in this new position. The member 17 now engaged bythe locking pawl 16 continues to move upwardly and causes the lever 29to be rotated clockwise about its pivot 31 until said lever abuts thestop position 45 on the periphery of the disk 40 at which time theupward motion of the member 17 is halted bringing the type E intoprinting position.

When 1 The cross head 10 continues up while the lever 13 yields underthe influence of spring 15. As the card continues under the brush theperforation at the 0 index point position causes another impulse to besent through magnet 27, the energization of which causes the disk 40 tobe advanced another notch in a counterclockwise direction presenting thestop position 46 to the contacting point ofthe lever 46. Said leverbeing now unsupported, the member 17 will move upward again under theinfluence of the spring 15 and will turn the lever 29 counterclockwiseuntil it abuts the stop position 46 at which point the type elementswill be brought to rest with the letter N in printing position.Following this, the perforation at the 11 index point position causes athird impulse to be sent through the magnet 27 which advances the disk40 another notch and presents the stop position 47 to the contact pointof lever 29 so that the member 17 rises slightly further turning thelever 29 until it rests on said stop position 47, which moves the typeelement W into printing position.

It will be seen therefore that with the first perforation only existingin the column, the letter E will be stopped in printing position; withthe first and second perforations only the letter N will be stopped inprinting position, while the three perforations mentioned are requiredto present the letter W for printlng.

When the cross head 10 reaches the top of its stroke printing iseffected in a manner to be described later. As the cross head descends acontact (not shown) is closed which completes a circuit through magnet54 thus energizing said magnet and attracting its armature lever 52,moving it clockwise about its pivot 53 and drawing the link 51downwardly. The pin '56 engages the pawl 38, withdrawing it from theratchet teeth 39 and the pawl'48 is turned clockwise about its pivot 49thereby disengaging said pawl from the ratchet teeth 44. The disk 40,being thus unrestrained is restored to its normal position by the spring43 and when the comb 1 1 restores the member 17 a projection 58 integralwith said member strikes the pawl '16 turning it counterclockwise torestore it to its latched position, the latch 33 being always biased tothe left by the spring 38.

Printing is effected by energization of a magnet 60 occurring when thecross head has reached the limit of its upward travel. When energizedsaid magnet attracts its armature 61 fixed to a lever 62 pivoted at 63,at one end, the other end being formed into a hook shape which coactswith a stirrup 64 which rests in an indentation in an extended arm 65integral with the lever 21. When the armature 60 is attracted thestirrup 64 is pulled downwardly causing the lever 21 to swingcounterclockwise about its supporting pivot 22, thus movthe gear 19 andrack 18 become disengaged,

and in order to prevent said disk from turning when disengaged there isprovided a brake 69 slidably fastened to the lever 21 by a pin and slotconnection 7 0. This brake is normally held in its up position (Fig. 1)by means of the spring 71. Touching the upper side of the brake is aroller 72, ournalled in a bifurcated end of a lever 73, pivoted at 74and biased in a clockwise direction by the spring 75. As the brake iswedge-shaped, there is an upward thrust against the roller 72 when thelever 21 is swung to the right. As the roller 72 is fixed against upwardmotion the brake 69 is forced downward against the type to lock the disk24 from rotating. The sideward thrust of the roller 72 is compensated bythe resilient spring 75.

Although a complete single printing section has been described it willbe understood that as many such sections as desired may be placed sideby side to print words or sentences in one printing operation.

WVhile there has been shown and described and pointed out thefundamental novel features of the invention as applied to a singlemodification it will be understood that various omissions andsubstitutions and changes in the form and details of the deviceillustrated and in its operation may be made by those skilled in the artwithout departing from the spirit of the invention.
